Print system

Abstract

In a print system includes a server holding an application program, in the client computer, when a print request is accepted for data obtained by the application program, an identifier in correspondence to the print request and a request to make print data for the data are sent to the server, while a print request, an identifier in correspondence to the print request, and print control information not dependent on the application program are sent to the printer. In the printer, when the identifier in correspondence to the print request accepted from the client computer is the same as that that received from the server, the print data is printed according to the print control information.

What is claimed is:  
     
         1 . A print system wherein a server holding an application program, a client system and a printer are connected through a network; 
 wherein said client computer comprises: 
 a receiver which accepts a print request for data obtained by the application program held in said server; and  
 a sender which, when the print request is accepted, sends an identifier in correspondence to the print request and a request to make print data for the data obtained by the application program to said server and sends a print request, an identifier in correspondence to the print request, and print control information not dependent on the application program to said printer; and  
 wherein said printer comprises: 
 a receiver which receives the identifier in correspondence to the print request and the print control information not dependent on the application program from said client computer and receives the identifier in correspondence to the print request and the print data from said server;  
 a comparator which compares the identifier in correspondence to the print request received from said client computer and that received from said server; and  
 an image forming unit which, when the identifier in correspondence to the print request received from said client computer is the same as that received from said server, prints the print data received from said server according to the print control information not dependent on the application program.  
 
   
     
     
         2 . The print system according to  claim 1 , wherein said sender in said client computer further sends a printer driver to said server, the printer driver comprises a program part only making the print data from the data obtained by the application.  
     
     
         3 . A computer connectable through a network to a server holding an application program and to a printer, comprising: 
 a receiver which accepts a print request for data obtained by the application program held in said server; and    a sender which, when the print request is accepted, sends an identifier in correspondence to the print request and a request to make print data for the data obtained by the application program to said server and sends a print request, an identifier in correspondence to the print request, and print control information not dependent on the application program to said printer.    
     
     
         4 . The computer according to  claim 3 , wherein said sender computer further sends a printer driver to said server, the printer driver comprises a program part only making the print data from the data obtained by the application.  
     
     
         5 . A program for image processing executable by a computer connected through a network to a server holding an application program and to a printer, the program comprising the steps of: 
 accepting a print request for data obtained by the application program held in the server; and    when the print request is accepted, sending an identifier in correspondence to the print request and a request to make print data for the data obtained by the application program to said server, and sending a print request, an identifier in correspondence to the print request, and print control information not dependent on the application program to the printer.    
     
     
         6 . The program according to  claim 5 , wherein in said sending step, further sending a printer driver to the server, the printer driver comprises a program part only making the print data from the data obtained by the application program.  
     
     
         7 . A storage medium storing a program executable by a computer connected through a network to a server holding an application program and to a printer, the program comprising the steps of: 
 accepting a print request for data obtained by the application program held in the server; and    when the print request is accepted, sending an identifier in correspondence to the print request and a request to make print data for the data obtained by the application program to said server, and sending a print request, an identifier in correspondence to the print request, and print control information not dependent on the application program to the printer.    
     
     
         8 . A printer connected through a network to a client computer and to a server holding an application program, comprising: 
 a first receiver which receives an identifier in correspondence to a print request and control information not dependent on the application program held in the server from the client computer;    a second receiver which receives an identifier in correspondence to the print request and print data from the server;    a comparator which compares the identifier received from the client computer and that received from the server; and    a print unit which prints the print data received from the server according to the print control information not dependent on the application program when the identifier received from said client computer is the same as that received from the server.    
     
     
         9 . The printer according to  claim 9 , wherein the printer exists in the same local area network as the client computer, and the printer communicate through a fire wall device and the Internet to the server.  
     
     
         10 . A program for image processing executable by a computer connected through a network to a server holding application programs, the program comprising the steps of: 
 receiving an identifier in correspondence to a print request and control information not dependent on the application program held in the server from the client computer;    receiving an identifier in correspondence to the print request and print data from the server;    comparing the identifier received from the client computer and that received from the server; and    printing the print data received from the server according to the print control information not dependent on the application program received from the client computer when the identifier received from said client computer is the same as that received from the server.    
     
     
         11 . The program according to  claim 10 , wherein the step of printing further comprising the step of deciding which control information has a priority when a plurality of control information not dependent on the application program exist in correspondence to the same identifier, and in said step of printing, the print data is printed according to the print control information having the priority.  
     
     
         12 . The program according to  claim 10 , wherein in the step of printing, when the print control information not dependent on the application program is not received, the print data is printed according to a default print control information.  
     
     
         13 . A storage medium storing a program executable by a computer connected to a network and holding application programs, the program comprising the steps of: 
 receiving an identifier in correspondence to a print request and control information not dependent on the application program held in the server from the client computer;    receiving an identifier in correspondence to the print request and print data from the server;    comparing the identifier received from the client computer and that received from the server; and    printing the print data received from the server according to the print control information not dependent on the application program received from the client computer when the identifier received from said client computer is the same as that received from the server.
